CVE-2025-8354
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA maliciously crafted RFA file, when parsed through Autodesk Revit, can force a Type Confusion vulnerability. A malicious actor may leverage this vulnerability to cause a crash, cause data corruption, or execute arbitrary code in the context of the current process.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA Type Confusion vulnerability exists in Autodesk Revit's RFA (Revit Family) file parser. When a maliciously crafted RFA file is opened, it triggers type confusion during parsing that can cause the application to crash, corrupt data, or execute arbitrary code within the current process context.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Autodesk Revit versionOpen Revit, go to Help > About Autodesk Revit, or check Add/Remove Programs in Windows Control Panel for the installed version numberAffected if Version is 2026.0, 2026.1, or 2026.2 (any version >= 2026 but < 2026.3)
-
Verify RFA file handling capabilityConfirm that Revit can open .RFA files - this is the Revit Family file format used for storing architectural componentsAffected if RFA file support is enabled (default state in Revit)
-
Determine if user handles RFA files from external sourcesReview workflows where RFA files from external or untrusted sources may be opened in the current Revit installationAffected if Users routinely open RFA files sourced from outside the organization or untrusted parties
Your environment is affected if Autodesk Revit version 2026.0 through 2026.2 is installed and users open RFA files, as the type confusion vulnerability in the RFA parser applies to this version range.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2026.3
Apply the Autodesk security patch when released; avoid opening RFA files from untrusted sources until the update is available.
Revit 2026.3
- Backup all Revit project files and custom families before performing any software updates
- Download Autodesk Revit 2026.3 from the official Autodesk website or your Autodesk Account
- Close any running instances of Autodesk Revit
- Run the installer for Revit 2026.3 and follow the installation prompts
- Restart your workstation after installation completes
- Launch Revit 2026.3 and verify that the application starts without errors
- Test opening previously used RFA family files to confirm normal operation
